Not getting coins

Im not getting coins. Seems to be glitch? Guy was in the gym for 5 hours. Should have 30 coins. Whats up? Kinda pisses me off. Regardless Great up date. Love the gyms. Its fun to fight in them again. Glad youre fixing bugs. Really want you to put out some clear instructions directions something. And seriously where are my coins????
